A realistic 3D model of a 2021 Volkswagen sedan, automatic transmission, in glossy black paint. The car should have detailed and accurate proportions, smooth curves, and clean geometry. Include high-resolution textures for the body, tires, headlights, and glass. Ensure reflections and material finishes are realistic: metallic black for the body, rubber for the tires, chrome details around the windows and grille. The model should look showroom-ready with good lighting and shading baked in.
